This is a three-strip foam kit for sealing the gaps around a window air conditioner. The L-shaped and flat polyurethane strips are pre-shaped, so you cut them to length and press them into the frame without tools. Frost King's kit does double duty: it blocks drafts and rattles and adds a light noise barrier. It suits renters and homeowners with a window unit who want a quick seasonal seal. Compared with generic foam tape, the shaped profiles fill corners and sills better, but the foam is soft and may compress or tear over a couple of seasons.

Owners of window AC units generally find the shaped foam easy to cut and fit, and say it quiets rattles and cuts drafts around the frame. Some report the foam is thin and flattens or loses grip after a season or two.
